Synopsis

CALL GAGETC (PNAM,CVAL)

C-Binding Synopsis

#include <ncarg/ncargC.h>

void c_gagetc (char *pnam, char *cval, int len)

Description

PNAM
(an input constant or variable of type CHARACTER) is a string three or more characters in length, the first three characters of which constitute the name of the internal parameter whose value is to be retrieved.
CVAL
(an output variable of type CHARACTER) is the name of a variable into which the value of the internal parameter specified by PNAM is to be retrieved.

C-Binding Description

The C-binding argument descriptions are the same as the FORTRAN argument descriptions with the following exception:

len
The size of cval as dimensioned in the calling program.

Usage

This routine allows you to retrieve the current value of Gridall parameters. For a complete list of parameters available in this utility, see the gridall_params man page.

Access

To use GAGETC or c_gagetc, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.

Messages
